Fusion x Whole Melt: Limited-Edition Extract Disposables

This page is a neutral, technical read for buyers and operators. We summarize what’s in the collab, how extract/coil pairing affects performance, which safety/transport documents matter, and how to verify them. No pricing or sales pitch—just the evidence you need to evaluate a limited run.

Limited artwork and curated extract profiles on a familiar 2 g platform.

For fundamentals and definitions, see our hub whole melt extracts disposable. This article focuses on the collaboration specifics and due-diligence workflow.

What’s in the Collaboration?

Positioning

Fusion × Whole Melt is a limited-edition series pairing curated extract blends with a compact, rechargeable 2 g disposable body. Expect rotating flavor art, batch-specific lots, and the same class of protections you’d see on mainstream 2 g devices.

What varies vs a regular 2 g?

Artwork/sleeves and flavor lineup are batch-driven.
Document packs (COA, battery/transport summaries) are still expected, but lot-matched to the drop.
Supply cadence is shorter—plan sampling and replenishment windows accordingly.

Extract & Coil Pairing (Why It Matters)

Performance hinges on the match between extract viscosity and atomizer design. Thicker live-resin or “liquid-diamond” blends favor porous ceramic or mesh-ceramic hybrids; terp-forward blends can run cooler. Start at the lowest profile and step up until flavor opens without browning. Use short preheat pulses (1–3 s) only when the device is cold; prolonged preheats can over-thin oil and induce flooding.

Tell-tale signs of a mismatch — persistent gurgle (flooding), scorched notes at modest voltage (wick too dry), or repeated first-puff clogs after cold storage. Adjust voltage, draw cadence, or preheat length before assuming a hardware defect.

Build, Battery & Protections

Modern 2 g disposables typically implement short-circuit and over-charge protection, basic thermal cut-backs, and airflow QC at end-of-line. For buyers, the actionable question is whether the batch includes traceable test summaries: battery safety, lithium transport, parcel packaging, and a lab COA for the extract lot.

Evidence Box: Compliance & Paperwork

Document	What to ask for	Why it matters
COA (Certificate of Analysis)	Accredited lab under ISO/IEC 17025; lot/batch match; potency panel; heavy metals; residual solvents; microbials as applicable.	Verifies composition and screens contaminants; 17025 signals the lab’s technical competence.
Battery safety	Report referencing IEC 62133-2 (Li-ion). Confirm cell model, report number, and test house.	Addresses abuse tests (short-circuit, over-charge, thermal) expected for portable secondary cells.
Transport (air/sea)	UN 38.3 Test Summary: manufacturer, model, test house, date; note T.1–T.8 (altitude, thermal, vibration, shock, short, impact/crush, overcharge, forced discharge).	Confirms cells/packs passed the UN design tests required for transport.
Small-parcel packaging	Summary to ISTA 3A or equivalent (drop, vibration, compression, low-pressure). Include product weight class and pass/fail notes.	Reduces in-transit damage and leakage risk in e-commerce parcel networks.
Electrical system practices	Design guidance aligned with UL 8139 where applicable.	Hazard-based safety approach for e-cigarette electrical systems (controls, protections, wiring).
Consumer warning (US-CA)	Evaluate applicability of Proposition 65; ensure final packaging warning is visible and lot/date marks are not obscured.	State-level chemical exposure warnings where required by law.

Keep a single PDF “doc pack” per lot (COA + UN38.3 TS + battery report + packaging summary). Use filenames with lot/date for traceability.

Reproducible Bench-Test Protocol

The following quick-turn protocol helps you validate a limited drop without lab gear. It is device-agnostic and intended for intake QC or buyer sampling.

Step	Method	Pass / Watch
Sample size	Randomly pick n = 10 units across at least 3 master cases.	n≥10 gives a quick read on lot variance; expand if defects >1.
Cold-soak check	Store at 5–10 °C for 2–3 h, then allow 15 min at room temp before first puff.	First-puff should not hard-clog. Watch: repeated clog on ≥2/10 suggests viscosity mismatch or insufficient preheat behavior.
Preheat behavior	Use short pulses (1–3 s) if cold; avoid chain preheats.	Oil visibly mobilizes without gurgle. Watch: audible boiling or flooding.
Low-power flavor open	Start at lowest profile; step up one notch at a time.	Flavor opens within 1–3 steps. Watch: harshness/browning at low settings → wick starvation.
Idle-leak	Stand units upright for 48 h at room temp, then inspect mouthpieces/airways.	No pooling; only minor condensation. Watch: visible seepage on ≥1/10 warrants holdback.
Label/trace	Scan QR or record printed lot/date; confirm match to COA.	All 10 map to the same lot used in paperwork.

Who It’s For / When It Makes Sense

Story-led rotations (collab shelves, seasonal displays) where artwork and limited flavors add lift.
Pilot runs before a private-label program, using the same base hardware but restricted sleeves.
Boutique retailers seeking short-cadence drops without rebuilding planograms.

Quick Comparison vs Standard 2 g

Aspect	Fusion × Whole Melt (Limited)	Standard 2 g
Extract	Curated, rotating blends; lot-specific COA	Stable SKUs across cycles
Hardware	Same class as mainstream 2 g; limited sleeves/art	Regular finishes; broader colors
Protections	Short-circuit, over-charge, thermal cut-back (varies by lot)	Similar feature set; often better documented
Docs	Lot-matched COA + UN38.3 TS + battery report; 3A parcel summary	Standardized doc packs per recurring production
Supply	Limited drop; shorter reorder windows	Ongoing availability for planograms

FAQ

Is this collaboration refillable?

No. It’s positioned as a sealed, single-use disposable. If you need refillable/pod systems, explore separate AIO platforms.

What documents should I request before purchase?

At minimum: COA (17025 lab; lot-matched), UN 38.3 Test Summary (battery/cell), IEC 62133-2 battery report, ISTA 3A packaging summary, and labeling check for Prop 65 where applicable.

How do I reduce clog/burn risk on thicker blends?

Store upright, use short preheat (1–3 s) only when cold, start at low profile and step up, and leave 20–30 s between puffs.
